T0 all whom t may concern:

Be it known that I, PAUL F. Cox, a citizen of the United States, and aresident of Chicago, in the county of Cool; and State of Illinois, haveinvented certain new and useful Improvements in Ventilators, of whichthe following is a specification, reference being had to theaccompanying drawings.

My invention relates to ventilators of a type especially designed foruse in the window of a sleeping carand it has for its principal objectthe provision of a form of device which shall be capable of beingcarried in an ordinary traveling-bag or suit-case, which shall have aneat appearance when out of use in condition for packing, and whichshall be effective for admitting and controlling tlie desired amount ofair. It is one of the specific objects of my invention to provide in adevice of this type for readily and easily closing the opening throughwhich the air is admitted, either partially or wholly as may be desired7without the necessity for removing the device from the window or forvarying the position of the sash in any way. It is another object of myinvention to provide suitable screens for preventing the admission ofdirt and dust, and to provide suitable means for deflecting the airupward at its point of admission. It is another object to provide adevice of this type of telescopic foi-m capable of being extended foruse in either direction whereby the air may be admitted at either sideof the window as may be desired at either side of the car. It is stillanother object of my invention to improve devices of this type in sundrydetails hereinafter pointed out. The preferred means by which I haveaccomplished my several objects are illustrated in the drawings and arehereinafter specifically described. That which I believe to be new anddesire to cover by this application is set forth in the claims.

In the drawings:

Figure 1 is a view showing a lower berth made up, with one of myimproved ventilators in position in the window at the eXtreme foot-endof the berth;

Fig. 2 is a View similar to Fig. 1, but showing the berth at theopposite side of the car, and showing one of my improved ventilators inposition at the foot, the telescopic ventilator being extended in theopposite direction from that shown in Fig. 1;

Fig. 3 is a perspective view of my improved ventilator when out of usein condition for transportation;

Fig. 4'is a vertical cross-section taken substantially on line 4`4 ofFig. 7 showing the ventilator in position in a window;

Fig. 5 is a view of my improved device as seen from outside the car, thecase being broken away in order better to show the construction, theview being taken substantially on line 5-5 of Fig. 4;

Fig. 6 is a vertical section taken substantially on line 6 6 of Fig. 4;

Fig. 7 is a view of my ventilator as seen from the right in Fig. 4 fromthe inside of the car, the casing being broken away; l

Fig. 8 is a vertical section through the ventilator with the casingremoved and with the device completely folded up ready for insertion inthe casing;

Fig. 9 is a fragmentary view showing the construction of the frame ofthe ventilator whereby the desired slots are provided; in the completedframe, the upper portion is grooved as indicated in Fig. 8;

Fig. 10 is a section taken on line 10-10 of Fig. 4, showing the mannerof connection of the deflector plate with the side members of thedeflector as hereinafter described;

Fig. 11 is a view of the spring pin by which the frame is held in thedesired position relative to the casing; and

Fig. 12 is a view similar to Fig 8, but

showing a modied form oflstructure.

Referring to Figs. 1 to 11, in which corresponding parts are indicatedby the same reference characters,-l5 indicates ,the casing which formstheouter telescopic member of my impro-ved device, the casing beingpreferably formed of tin or aluminum. The other member which is adaptedto fit snugly within the casing 15 is in the form of a frame comprisingends 16-17 and side bars 18-19. As is best shown in Figs. 3 and 9, theend pieces 16 and 17 are formed in three separateA pieces so as toprovide slots 20-21, the side bars 18 and 19 being lgrooved, as isclearly shown in Fig. 8, such grooves being in registration with theslots 20-21. A screen 22, preferably formed of a fine wire netting, isslid into position in the slot 20 of the frame, being of sufficient sizeto cover the frame completely from end to end. A slide 23 is slidablymounted in the slot 21, being also of a. size to fill the framecompletely from end to end.

A defiector plate 24 is swingingly mountone side so as to permit thedeflector plate 2st to swing outward from the position shown in Fig. 8to the position shown in Fig. The deflector plate 211s preferably formedot metal plate bent at its ends to embrace the edges of suitabletriangles` 27 formed of cloth or other pliable material (see Fig. 10).he rear edges of the triangles are secured to the end bars ot' the frameby means of tacks or in any other il curtain 28 formed of cloth or anyother suitable pliable material is connected at its upper edge to thebar 18 of the frame, being y.adapted to hang straight vdownward betweenthe deiiector plate EZ/-l and the 'slide 23 as shown in Fig. 8, or toextend outward over the edge of the delector plate 2st when such plateis swung into the position shown vin Fig. d. rlhe curtainv 28 isprovided at itslower edge with a bar 29 of any suitable type adapted tobe of sutiicient weight for holding the curtain 28 nicely in position.r1`he channel 25 is preferably provided with slots 30 for the escape ofdirt and dust as hereinafter described. rThe upper edge off the curtain2S in the construction show-n is secured in position by means of achanneled member 31 which embraces the bar 18. The channel member 31 isprovided with a groove in its web portion for the reception ot' a stripof elt32.

When the 'frame with the several parts carried thereby as abovedescribed is in position within the c sing 15 as shown in Fig. 23 itisadapted to be secured in position therein by means of a pin 33 extendingthrough a hole 34 (see Fig. 3) at one end of the casing anda-registering' hole 35 in the corresponding end of the frame. 1t isevident, however, that even without the` use of the pin 38 the frictionot' the 'strip 32, which is then compressed, against the upper wallofthe casing 15, will tend to hold such Aframe in place within thecasing.

1Whenever it is desired to insert the ventilator in a window, the pinS23-.is removed and the trameV is drawn from either end of the casing asmay be desired, depending upon whether the casing is to be placed at theside of the window which isv in advance or vat the rear in the movementor the train. "When the sash of the window, such as that indicated by 36in Fig. Lhis raised sutilciently, the frame is drawn out from the casingso as to bring the end of the frame of 'the ventilator against one sideof the frame of' the window while the end of the casing is against theopposite side of the frame of the window, the pin 33 being then:inserted through registering openings 34: and 35 so as to hold theventilator against withdinwal, the sash being then lowered into contactwith the casing 15 and the strip of felt which expands suiliciently toprovide a close lit. The de'liector plate Q-i is then drawn out into theposition shown in Fig. 4f, and the curtain 28 is lifted out of the wayso to permit the desired adjustment oi the slide 23. By means of groovesor notches 37, or any other suitable means upon the slide 23,. the slideis moved into position toy leave just as great an vopening for theadmission of air as may be desired. The curtain 9,8 is then extendedoutward over the upper edge of the deilector plate as shown in Fig. el.will be readily understood, if it is desired at any timeto vary theamount ot airbeing admitted, this can be accomplished by merely raisingthe curtain 2S and moving the slidb 23 Vas mayl be desired. A furthercontrol of the amount of air being admitted to the berth is providedthrough the adjustment of the deliector plate 2l 1n the constructionshown, no means is provided for holding the deiiectorplate in ditl'erentadjusted positions other-than by the. Contact out the curtain 28 uponthe plate.

Q By the use of the double screen construction such as is providedby-thevscreen 22 directly within the opening below the sash and thesecond screen comprising the triangular pieces 27 and the-curtain 28,the force 'of the airis broken andthe dirt and dust carried by theairare prevented from entering the berth. ,1N hen-the ventilator `is beingtaken from the window, suchdirt and dust as may have gathered betweenthe deflector plate 2e and the screen 22 is adapted to pass downward forescape through the slots-30- in the channel member '25.

lin vthe 4construction shownin Fig. 12, a frame SSis eniployed similarin a general way tothe frame vabove described provided with slots and`grooves tor theinsertion of ya screen 39 and a vslide 110. A piece ofrubber tubingelsecured. upon-the upper edge of the frame takes` theplacev of the strip ot telt 32 of the construction first described. Theframe SS-is tol be contained in a casing such as the casing 15 abovedescribed. rlhe form of device shown inFig. 12 is capable of beingproduced very cheaply and is a ltorm having considerable merit'asaventilator, even though 4notinvolving all Vof the advantages of theconstruction first Ydescribed. It is believed that f theoperation of thedevice of Fig. 12 will be readily understood ywithout -aturtherdescription.
